Novel high-performance durable concrete formula for large-span bridge
The invention relates to the technical field of concrete, and discloses a novel high-performance durable concrete formula for a large-span bridge, which comprises the following components: cement, sand, gravel, water, an admixture, an additive, steel fiber and polyacrylonitrile fiber in a ratio of 445: 633: 1033: 156: 78: 6.864: 78: 0.89. The formula development of the novel high-performance durable concrete provided by the invention not only plays an important role in guaranteeing the engineering quality of an ultra-long and large-span bridge concrete structure, but also can remarkably improve the durability of a long and large bridge efficient concrete structure, construct a durable concrete structure, prolong the safe service life of engineering and reduce the construction cost. Maintenance and repair cost during later use is greatly reduced, continuous and safe use of the long and large bridge within the designed service life is guaranteed, and therefore the investment benefit of a project is improved.
本发明涉及混凝土技术领域，公开了一种大跨径桥梁新型高性能耐久混凝土配方，包括如下配比，水泥∶砂∶碎石∶水∶掺合料∶外加剂∶钢纤维∶聚丙烯腈纤维为445∶633∶1033∶156∶78∶6.864∶78∶0.89。本发明所提供的新型高性能耐久混凝土配方研制不仅对保证超长、大跨径桥梁混凝土结构的工程质量发挥重要作用，而且必将显著提高长大桥梁高效混凝土结构的耐久性，建造可持久的混凝土结构，延长工程的安全使用寿命，大大减少后期使用时的维护、维修费用，保障长大桥梁在设计使用年限内连续、安全的投入使用，从而提高工程的投资效益。
